There are seven Regional Transport Partnerships in Scotland (RPTs). The role of partnerships is to strengthen the planning and delivery of regional transport developments. The first task of each RTP was to prepare a regional transport strategy. This is supported by a delivery plan where RTPs set out when and how projects and proposals would be delivered. Some RTPs are also responsible for the delivery of transport services. In particular Strathclyde Partnership for Transport owns and operates the Glasgow subway and major bus stations across the west of Scotland.
